I have a 1998 ford van that the mechanic says the engine block is
Cracked. When you pour water in the radiator it runs straight to the oil
Pan. Is there any sealer on the market that might get it a temporary fix.
It's a v/6.

Go to Lowe's or depot and git some JD Weld regular if you have an internal crac I don't think you can get a it-get onother opinion...

No..
